Comparison of the effectiveness of enhanced cognitive-behavioral couple therapy on emotional self-regulation and couple burnout of self-assigned and court-referred incompatible couples.

This study aimed to investigate the comparative effectiveness of enhanced cognitive-behavioral couple therapy (ECBCT) on emotional self-regulation and couple burnout in incompatible couples. The study hypothesizes that ECBCT is efficacious in emotional self-regulation and marital burnout of incompatible Iranian couples (self-assigned and court-referred) visiting counseling centers. Twenty-eight Iranian couples were divided into four groups (two self-assigned and court-referred experimental groups and two self-assigned and court-referred control groups) who were selected using the available sampling.

Tailoring Single-Mode Random Lasing of Tin Halide Perovskites Integrated in a Vertical Cavity.

The development of random lasing (RL) with predictable and controlled properties is an important step to make these cheap optical sources stable and reliable. However, the design of tailored RL characteristics (emission energy, threshold, number of modes) is only obtained with complex photonic structures, while the simplest optical configurations able to tune the RL are still a challenge. This work demonstrates the tuning of the RL characteristics in spin-coated and inkjet-printed tin-based perovskites integrated into a vertical cavity with low quality factor.

Topical skin adhesives for laceration repair in children.

Question: A 4-year-old child presented to my office recently with a 2-cm forehead laceration. The child had needle phobia and was very upset, so suturing in the office might have been very challenging. The parents were also concerned about the use of suture.

Purcell Enhancement and Wavelength Shift of Emitted Light by CsPbI Perovskite Nanocrystals Coupled to Hyperbolic Metamaterials.

Manipulation of the exciton emission rate in nanocrystals of lead halide perovskites (LHPs) was demonstrated by means of coupling of excitons with a hyperbolic metamaterial (HMM) consisting of alternating thin metal (Ag) and dielectric (LiF) layers. Such a coupling is found to induce an increase of the exciton radiative recombination rate by more than a factor of three due to the Purcell effect when the distance between the quantum emitter and HMM is nominally as small as 10 nm, which coincides well with the results of our theoretical analysis. Besides, an effect of the coupling-induced long wavelength shift of the exciton emission spectrum is detected and modeled.
